I know English and Spanish, and I'm trying to learn Latin. I can't imagine learning more than three languages, it's so hard for me to learn a new language. I know a lot of people who are fluent in two languages, and a handful of people who know three languages, but I've never met anyone who knew four or more languages. Do any of you know more than three languages? What's your secret? Is it just easy for you to learn languages, or did you struggle through it?
